Plain-English summary
A group of 12 cats showed sudden signs of back problems, including difficulty walking and urinary incontinence, likely due to intramedullary intervertebral disc extrusions (a type of spinal injury). Most of these cats had a history of trauma, and MRI scans confirmed the diagnosis. After treatment, all non-walking cats regained their ability to walk, and all cats either kept or regained control over their urination. Most of the cats were doing well at follow-up visits, indicating a positive outcome from their treatment.

Abstract
ObjectivesThis study aimed to describe the clinical characteristics, MRI findings, treatment and outcome in cats presumptively diagnosed with intramedullary intervertebral disc extrusions.MethodsA retrospective review was conducted of medical records and MRI data from cats presumptively diagnosed with intramedullary intervertebral disc extrusions. Long-term outcome (⩾6 months) was assessed through medical records, questionnaires completed by the owners or both.ResultsA total of 12 cats met the inclusion criteria. All presented with peracute or acute clinical signs, with nine having confirmed (n = 3) or possible (n = 6) external trauma based on history, physical examination or MRI findings. Seven cats were ambulatory and five were non-ambulatory. Eight cats presented with urinary incontinence; none exhibited faecal incontinence. Neuroanatomical localisation included the T3-L3 (n = 7) and L4-S3 (n = 5) spinal cord segments. MRI showed an intramedullary intervertebral disc extrusion at the following sites: T12-T13 (n = 1), T13-L1 (n = 1), L1-L2 (n = 2), L2-L3 (n = 2), L4-L5 (n = 3) and L5-L6 (n = 3). All cats underwent treatment and were discharged after a median hospitalisation time of 4 days (range 3-14). All non-ambulatory cats with available follow-up information (4/5) regained ambulation by the time of the short-term (<6 weeks) or long-term (⩾6 months) assessment. Moreover, all cats either retained or regained urinary continence by the time of discharge, the short-term (<6 weeks) or the long-term (⩾6 months) assessment. Overall, nine cats achieved a successful outcome and were considered functional pets at the short-term (<6 weeks) and/or long-term (⩾6 months) follow-up. Two cats were lost to follow-up, and one cat had perceived persistent generalised discomfort.Conclusions and relevanceMost cats presumptively diagnosed with an intramedullary intervertebral disc extrusion showed a favourable outcome with treatment in this study. This condition should be considered in cats presenting with peracute or acute signs of T3-L3 or L4-S3 spinal cord dysfunction, especially if there is a history or indication of trauma.
